CALENDAR-CLOCK.

SPECIFICATION forming part of Letters Patent No. 704,916, dated July 15,1902.

Application filed May 3, 1901. Serial No. 58,605. (lilo model.)

To all whom it may concern.-

Be it known that 1, JOHN 1. PEATFIELD, a citizen of the United States,and a resident of Arlingtomin the county of Middlesex and State ofMassachusetts, have invented a new and Improved Calendar, of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in automatic calendars; and theobject is to provide a calendar that shall be practically perpetual,that will require no manual setting or regulating excepting in thewinding of its motor at intervals of a year or more, and to so arrangeit that it may be controlled by an ordinary clock mechanism for changingthe date and day indicators every twenty-four hours, and, further, toprovide a simple mechanism for making the changes from mouth to monthand the dates from the short months to the first day of the next month.

I will describe a calendar embodying my invention and then point out thenovel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a perspective view of a calendar embodying my invention.Fig. 2 is a front elevation with the casing removed. Fig. 3 is an endelevation and partial section of the calendar. Fig. 1 is an endelevation opposite that of Fig. 3. Fig. 5 is a sectional elevation onthe line 00 of Fig. 3. Fig. 6 is a rear elevation showing means foroperating the calendar hand and-pointer. Fig. 6 is a detail showing atripping mechanism employed. Fig. 7 is an elevation, partlyin section,showing a calendar-wheel and operating mechanism therefor. Fig. 8 is aface view of the calendar-wheel. Fig. 9 is a plan View thereof. Fig. 10is a section on the line 3 y of Fig. 7. Fig. 11 is an edge view of aworm employed. Fig. 12 is a detail view of a detent employed. Fig. 13 isan elevation showing connections with a clock mechanism. Fig. 14. is anelevation, partly in section, showing a modification. Fig. 14 is adetail view of a cam mechanism employed in the construction illustratedin Fig. 14. Fig.

15 is an end elevation of the construction shown in Fig. 14, and Figs.16 and 17 show in plan the date-calendars of this modification.

Referring to the drawings, 1 designates a casing of any suitablematerial, arranged on the front wall of which is adial 2, and aroundthis dial a hand or pointer 3 moves. The dial is provided with a row offigures indicating dates. Arranged in the front of the casing is asightopening -1-, through which the month-indicator may be seen, andalso a sight-opening 5, through which the day-ofthe-week indicator maybe seen.

Arranged within the casing is a frame com prising a front plate 6 and aback plate 7, and mounted to rotate between these plates is a drivingmechanism consisting of a master wheel 8, mounted on a shaft 9, andconnecting with said shaft is one end of a spring 10, the other end ofsaid spring being secured to a cross-bar 11. As the movement of themachine only takes place once in every twentyfour hours, it will not benecessary to wind the spring more than once a year. To permit thewinding of the spring, the masterwheel 8 is loosely mounted on the shaftand has a pawl 12 for engaging with a ratchetwheel 13, secured to theshaft. This masterwheel meshes with a pinion 1 1, on the shaft of whichis a gear-wheel 15, meshing with a pinion 16 on a shaft 17, and on thisshaft 17 is a gear-wheel 1S, meshing with a pinion 19, on the shaft ofwhich is a gear-wheel 20, which engages with a pinion 21 on the shaft ofthe governor or fan 22.

The hand or pointer 3 is mounted on a shaft 23, and 011 this shaft isfixed a stop-wheel 24, having a number of notches in its-periphery equalto the number of days in the longest month-that is, thirty-one. Alsoconnected to the shaft is a ratchet-wheel 25, engaged by a pawl 26,mounted on an arm 27, arranged to swing on the shaft 23. From the outerend of this arm 27 a draw-rod 28 extends upward and connects at itsupper end with a bar 29, mounted to swing on a stud 30 and carrying aroller 31, which is engaged by a cam 32.

The holding-dog for the wheel 2a consists of a bar 33, adapted to engageits lower end in any one of the notches. This holding-bar is connectedat its upper end to a rod 34, mounted to swing on the stud 30, andprojected over the shaft on which the cam is mounted and adapted toengage with this bar 34 is a finger 36, which is connected to the shaft35. By this arrangement when the driving mechanism is started, as willbe hereinafter described, the finger 36 will swing the bar 34 upward,and consequently lift the holding-bar33outofanotchofthewhee124. Then asthe shaft 35 continues to rotate, the cam 32, engaging with the roller31, will raise the parts 29 and 28, swinging the arm 27 upward, so thatthe pawl 26 will move the hand or pointer through one space, or from onefigure or date to the next higher figure or date.

Extended across the front of the front plate 6 is a shaft 37, designedto operate the cylinders 38 and 39, having bearings in upward extensionsof the frame. The cylinder 38 has marked upon it the months of the year,while marked upon the cylinder 39 are the days of the week, designed tobe brought successively to View at the sight-openings. The shaft 37 isrotated by means of a bevel-pinion 40, connected to the end of the shaft17 (indicated in dotted lines in Fig. 2) and meshing with a bevel-pinion41 on said shaft 37. Arranged on the shaft 37 is a worm 42, which mesheswith a worm-wheel 43, on the shaft of which is a holdingdisk 44,provided at one side withanoutwardly-openingnotch45. The worm 42 has astraight portion for about onequarter of its circumference, so thatwhile said straight portion is moving between teeth of the worm-wheel nomotion will be imparted to said wheel, and consequently the disk 44 willbe held stationary for a time sufficient to permit a finger 46 to dropinto the notch 45. This finger 46 is mounted on a swinging rod 47, andthe outer end of this swinging rod passes through a loop on alifting-rod 48, pivoted on a stud 49. Carried by this lifting-rod 48 isa pulley 50, designed to be engaged by a cam 51 on the counter-shaft 37,and pivotally connected to this lifting-rod is an upright rod 52,pivotally connected at its upper end to an arm 53, which, as shown, ismade in the form of a boxing and mounted to swing on theoutwardly-extended shaft of the cylinder 38; and carried in this arm orboxing is a pawl 54 for engaging with a ratchet-wheel 55 on the shaft ofthe cylinder, and also mounted on said shaft is a stop wheel or disk 56,having notches in its periphery equal to the number of teeth of theratchet-wheel. Adapted to engage in these notches is a dog 57, attachedto the upper end ofa rod 58, connected to a sleeve 59, adapted to rockon the stud 49, and extended outward from this sleeve 59 is areleasing-arm 60, adapted to be engaged by a finger G1 on the end of thecounter-shaft 37. This lifting-arm 60 is provided at its free end with aweight, so as to insure the rocking of the dog 57 into engagement withthe stop-wheel. However, a spring may be used for this purpose, ifdesired.

It is necessary that the dog 57 of the looking device shall movesuddenly out of and into engagement with the wheel. while theratchet-wheel is idle, thus precluding any possibility of the cylindermoving out of position when shaken about, as at sea or in arailway-carriage. In order to secure this result, the disk 56 of thelocking or holding device is made larger than the ratchet-wheel, thuscausing the corresponding number of equal divisions on each to vary indistance in proportion. A similar mechanism for operating the uppercylinder 39 is arranged at the opposite end of the machine that is, Ipro vide for engaging in any one of the notches of the stop or lookingdisk 61 on the extended shaft of the cylinder 39a dog 62, mounted on anarm or rod 63, adapted to swing on a stud 64, and the forward end ofthis arm or rod 63 is connected to a lifting-rod 65, the lower end ofwhich is connected to an arm 60, swinging on a stud 67 and adapted to beengaged by a finger 68 on the end of the counter-shaft 37. Mounted toswing on the extended shaft of the cylinder 39 is an arm or boxing 69,carrying a spring-pressed pawl 70, which engages with a ratchet-wheel71, fixed to said shaft. From the arm or boxing 69 a rod 72 extendsdownward and connects at its lower end with a swinging bar or arm 73,carrying a roller 74, adapted to be engaged by a cam 75 on thecounter-shaft 37. The arm 73 is connected to and moves with a rock-shaft76, and on the inner end of this rock-shaft is an outwardlyextendedretarding-finger 77, the outer end of which is adapted to engage with ahooked or cam-shaped finger 78, mounted to rock on a stud 79, andextended from the sleeve of this cam-finger is a weighted arm for movingsaid cam-finger to its normal position, as indicated in Fig. 2. Alsoconnected to the sleeve of the cam-finger is a pinion 81, with which asegmental rack 82 engages. This segmental rack is carried on the outerend of a rock-shaft 83,having bearings in the machine frame. Extendedfrom this rock-shaft 83 is a stop-rod 84, designed to engage with a pin85 on the gear-wheel 1S, and also extended from the shaft 83 is an arm83, which engages with a lifting-cam 84 on the shaft 17.

Extended from a rock-shaft S6 is a liftingfinger 87 for engaging withthe stop device 84, and also extended from said rock-shaft 86 is aretarding-finger 88, designed to momentarily engage with a pin 89 on thegearwheel 20. Attached to the outer end of this rock-shaft 86 is an arm90, from which a lifting-rod 91 extends downward to a connection withaswinging arm 92, arranged on the timemechanism frame, and this arm 92carries a finger 93, which is engaged bya cam 94, which will operateevery twenty-four hours to lift the rod 91 upward, consequently rockingthe shaft 86, which through the medium of the finger 87 will lift theholding device 84 out of engagement with the pin 85, and at the sametime the finger 88, carried by the rock-shaft 86, will move into theline of movement of the pin 89, as indicated in dotted lines in Fig.

IIS

5. This'will momentarily hold the train of gearing until the hook end ofthe holding device 84 is entirely free from the pin 85, after which theparts will drop to their normal position, with the finger 88, asindicated in full lines, out of the line of movement of the pin 89.

The operation of the device as so far described is as follows: When therock-shaft 86 is operated as just described, the mechanism will bestarted and the rotation of the shaft 37 through the medium of its camwill rock the arm 69, sothat the pawl 70 will rotate the cylinder 39through onespace of the ratchet-wheel with which the pawl engages.Before this movement, however, the pin 68 on the shaft 37 by engagingthe arm 66 will raise the dog 62 out of engagement with thelocking-wheel 61. It will immediately fall, however, and rest upon theperiphery of said locking-wheel until another notch of the locking-wheelcomes in line with the dog, when it will drop therein.

During the movement of the upper cylinder, or that having the daysmarked thereon, it is necessary that the month-carrying cylinder shouldremain at rest until the end of the month. Therefore the finger 46 isdesigned to rest upon the periphery of the wheel 44. When so resting onthe periphery, it will prevent a downward movement of the rod 52suflicient to cause the pawl 54 to engage with a new tooth of theratchet-wheel 55. In other words, this pawl will slide back and forth onthe periphery of the ratchet- Wheel without imparting motion theretountil the disk 44 is rotated once around to bring the notch 45 into theline of movement of the finger 46, when said finger by dropping thereinwill permit a sufficient downward movement of the arm 53 to cause thepawl carried thereby to engage with a tooth of the ratchetwheel 55, sothat the cam 51 will rotate the cylinder through the space of one step.

It will be noted that the teeth of the wormwheel 43 are so arranged ornumbered thata complete rotation of the disk 44 takes place only once inthirty-one days.

Mounted to rotate in the frame is what I term a four-year wheel 95,having segmental channels 96 in its periphery, and projected outwardfrom one side near the periphery of the wheel are lugs 97. There aretwenty of these lugs on this side of the wheel, and on the opposite sidethere are three outwardlyextended lugs 98, 99, and 100. Extended acrossthe slot in the periphery of the wheel,

in line with the lug 98 and in line with the lug tion around its axisand also a transverse rotary motion.

It is mounted in a frame consisting of a disk 104, (see Fig. 7,)connected to the shaft 105, on which the worm-wheel 43 is mounted, andto arms 106, extended from the disk 104, is attached a cross-arm 107.This four-year wheel is designed to have a complete axial rotary motiononce in four years, or forty-eight months. I therefore provide it on oneof its surfaces with forty-eight pins or teeth 108, which are engaged bya worm 109, mounted on a shaft 110, having a bearing at one end in thedisk 104 and at the outer end in an arm 111, extendedfrom one of therods 106. This worm 109 is straight for approximately one-tenth of itslength. This is so that at certain times no movement will be impartedaxially to the wheel 95, giving certain parts a sufficient time to moveinto and out of the slots 96. On the shaft 110 is a pinion 112, whichengages with a stationary gear 113, this stationary gear being attachedto the sleeve in which the shaft has its bearing. Consequently as theframe, with the disk 104, moves around motion will be imparted to theshaft through the medium of the gear connections, thus imparting theaxial rotary motion around the axis 105, while the transverse motion isimparted by the shaft 105.

Extended from the rock-shaft 83 is a hammer-rod 114, carrying at itsfree end a hammer115, which is adapted at certain times, as will behereinafter mentioned, to engage with the four-year wheel. Thisfour-year wheel is particularly designed for governing the movements ofthe date-indicating hand from thirty-day months to the first of the nextmonth and also for causing the hand to jump a sufiicient number of datesat the end of the three Februarys occurring in four years. Thebridge-blocks arranged in the wheel represent the months of February asjust closed. For instance, at the end of February having twenty-eightdays the four-year wheel will have been axially rotated until theprojection 98, the bridge-block 101, and the forward pro jection 97 comeinto the line of movement of the hammer -that is, at the end of the 28thday of February the clock mechanism before referred to will start themotor for the calendar and the hammer 115 in descending will firststrike upon the lug or projection 98, then upon the wheel, thebridge-block, and the front projection, thus holding the stop device 84out of engaging position with the pin 85, permitting the calendar motoror mechanism to operate a sufficient length of time to move theindicating hand from February 28 to March 1. The leap-year Februaryhaving twenty-nine days, it is of course not necessary for the machineto run so long, as above described. Therefore there is no lug orprojection similar to 98 and 99 opposite the bridge-block 103. In movingthe hand from the thirtieth of a month to the first of the next month itmust of course jump over the 31 of the dial. Therefore when the hammerfalls it will first strike upon the periphery of the four-year wheel andthen upon its next down- ITO ward movement will strike a lug 97, so thatthe mechanism will continue to rotate until the indicating-hand reachesthe figure 1. The four-year wheel also governs the action of thecylinder carrying the days of the week, inasmuch as when the hammer isheld up by the wheel the pawl is held up, or, in other words, is notpermitted to fall far enough to engage or catch a tooth on theratchet-wheel, so that the names of the days of the week are given inperfect succession regardless of the number of revolutions the machineis required to make in order to represent the corresponding date.

As has been before stated, the operation of the worm 109 is notcontinuous, but intermittent in its action. When the upper face of thewheel 95 passes under the hammer, the worm causes the wheel to remain atrest in its transverse direction just long enough for the wheel to passunder. I will here state that the wheel 95 is mounted eccentrically onits axis 105 so that the upper side just referred to has the lesserdiameter.

The means for preventing the movement of the pawl sufi'iciently downwardto engage with a tooth of the ratchet-wheel comprises the cam-finger 78.For instance, when the hammer drops into a slot or comes home,as mightbe said, the cam-finger oscillates to its full extent and allows the baror finger attached to the rock-shaft to drop home also; but if thehammer rests upon the rim of the fouryear wheel the segment-gear 82 willtravel in the same proportion, thus preventing the camfinger fromoscillating to its full extent, and so intercept the rock-bar andprevent it from falling home. This holds or prevents the pawl frommoving sufiiciently downward to engage with a new tooth of theratchet-wheel.

In Figs. 14 and 15 instead of employing a hand or pointer movable over adial for indicating the dates I employ two date-cylinders 116 and 117,the cylinder 116 being arranged within the cylinder 117. These aredesigned to rotate independently one of the other at certain times andat certain times to rotate together. The outer disk is provided withthree openings spaced about equally around its circumference, and neareach opening are two date-figures, while the inner cylinder has threerows of date-figu res, which are designed to be disclosed through theopenings 118, 119, and 120 of the outer cylinder. An illustration of theworking of this device maybe given as follows: To start correctly, inorder to pass in succession over the thirty-one days of a month set theouter cylinder with its date 1 directly over the date 3 of the innercylinder. 1 will here state that the sightopening in the casing for thisdate-indicator is made of a sufficient length to extend en tirely acrossthe cylinders. Having set the date 1 over the date 3, the date 31 willshow through the opening at the righthand end,and the date-figure 1 ofthe outer cylinder will be below the line of said opennone-1e ing. The31 now seen represents the last day of the previous month. Now byturning both cylinders together, as will be hereinafter described, the31 disappears, and the 1 of the outer cylinder shows on the left end ofthe opening in the casing, representing the first day of the new month.I The figures will appear at the opening in succession by turning theouter, inner, or both cylinders. To be more exact, I will state theorder of turning the cylinders. To bring the date 1 to view, bothcylinders are turned together. To bring the dates 2 and 3 to View, theouter cylinder is to be turned, which will bring the date 3 to Viewthrough the opening 118. Now the dates 4 to 11, inclusive, are broughtto view byturning the inner cylinder. The date 12 is brought to view byturning both cylinders together, and

13 and 14 are brought to view by turning the outer cylinder alone, whilethe turning of the inner cylinder brings to view successively thedate-figures 15 to 22, inclusive. Now as 23 is to be next brought toView both cylinders are to be turned together, and this is also theoperation when the dates 24: and 25 are to be brought to view, and thenthe dates 26 to 31, inclusive, are brought to view by turning the innercylinder.

The mechanism employed for rotating the cylinders is somewhat similar tothe devices for rotating the date and month cylinders first described.The outer cylinder 117 has at one end a tubular trunnion 121, throughwhich the shaft 122 for the inner cylinder passes. At the end oppositethe trunnion 121 the outer cylinder is mounted to rotate on the shaft122. Attached to the tubular trunnion 121 is a stop or locking wheel123, provided with a series of notches similar to the stop or look wheelfirst described, and also mounted on this trunnion is a ratchet-wheel124, which is engaged by a pawl 125, carried by a rocking arm 126, fromwhich a liftingrod 127 extends downward and has at its lower end aroller 128 for engaging with a cam 129 on the shaft 130, which issimilar to the counter-shaf t first described and operated in the samemanner.

Coacting with the stop or lockin g wheel 123 is a locking-dog, which iscarried by a rockarm 131, from which a rod 132 extends downward to aconnection with a swinging arm 133, adapted to be engaged by a lug orfinger 134 on the shaft 130, so as to raise the dog out of engagementwith the stop or locking wheel.-

The rod 127 is held in its positions by means of a swinging rod 135,this construction being similar to that shown in Figs. 3 and 4. Thisswinging rod projects through an opening in the yoke or casting in whichthe roller 128 is pivoted, and engaging with this projected end of therod is a detent-finger-carrying rod 136, which is pivoted on a stud 137and has a finger 138, the purpose of which will be hereinafterdescribed.

IIO

stud 137 and has a detent-finger 153.

On the outer portion of the shaft 122 is a stop or looking wheel 139,similar to the wheel 123, and coacting therewith is a dog 140, mountedon a swinging arm 141, from which a rod 142 extends downward to aconnection with a swinging arm 143, designed to be engaged with a finger144 on the counter-shaft, and also attached to the shaft 122 is aratchetwheel 145, which is engaged by a pawl 146, carried on an arm 147,from which a rod 148 extends downward and carries at its lower end aroller 149, which engages with a cam 150 on the counter-shaft. A rockingrod or arm 151 passes through the casting or yoke for holding the roller149, and engaging with its projected end is a detent-finger-carrying armor lever 152, which is mounted on the Instead of the disk 44, as beforedescribed, I mount on the shaft 105 two disks 154 and 155. The disk 154is provided with two projections 156, the space on the periphery of thewheel at one side of said projections being considerably longer than thespace between the projections at the opposite side. The disk 155 isprovided at equally-distant points with notches 157. v

In the operation, assuming that the date 31 is now at the sight-openingin the easing and it is desired to move or bring the date 1 into view,as has been before described, the disk 155 will be in a position topermit the finger 138 to drop into one of the notches 157, thuspermitting the pawl 125 to fall sufficiently to engage a tooth of theratchetwheel, so that on an upward movement imparted by the cam 129 theouter cylinder will be rotated, bringing the 1 into view. The notch 157is sufficiently wide to again permit the finger 138 to fall into thenotch when the change is to be made from 1 to 2, and this operation willbe carried out as has been described.

Monthand day cylinders are arranged some- What similar to the cylinders116 and 117 and are operated by similar devices, portions of thesedevices being shown at the right-hand .side of Fig. .14, excepting inthis case the parts are controlled from an arm or lever 158, having afinger for engaging in a notched disk 159 on the shaft 105. This arm orlever is connected to the part carrying the roller 160 by a rod 161,having a slot in which the earn 162 may pass.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.
